SYSTEM AND METHOD FOR USING LAYERS AND GRIDS TO ACCESS, VIEW, EDIT AND STORE DIGITAL MAP DATA
First Claim
1. A system for using layers and grids to access, view, edit and store digital map data, comprising:
- a set of map data that corresponds to a digital map, and having a first map format associated therewith, and multiple levels of map information stored therein;
a first map legend that is associated with the first map format and that links displayable map item types in the first map format to a universal display format;
a display device including a graphical window that is used to display the digital map in a universal display format; and
a user interface that allows an operator to select a level of the map to be currently displayed on the display device, and wherein the system automatically uses the map legend to interpret the features included therein, and output feature information for that level of the map.

Abstract
A system and method for using layers and grids to access, view, edit and store digital map data. An embodiment of the present invention is generally related to systems for accessing, displaying, editing and using digital maps. The system assists in previewing and outputting data to different map formats. Some maps include multiple levels of tiled map information. The map can be displayed on a display screen in a universal display format that is independent of the original format, and can then be parsed using a map legend. Features are provided to allow output of different types or sets of map data based on the currently displayed map. If a user modifies the map display to display a greater, or lesser, detail of resolution, then the set of map data that is output can be varied accordingly.
